We supply a full box of dishwasher packets, laundry detergent, paper towels, toilet paper, sugar, salt, and so forth just as if we were living in the house ourselves. We also make sure there's some coffee, pasta, and cooking oil in the cupboard. We put ourselves in the shoes of an arriving guest, and provide them what they will need, and perhaps a bit more.
None of our over 1000 guests have abused our supplies. Few of our guests get snarky without cause. Those that do get a bad review.
Hospitality, says my dictionary, is the friendly and generous reception and entertainment of guests, visitors, or strangers.
